Small pit at Pla d'Ardenya (Vallirana), with a circular entrance one metre across, a 4-metre shaft and a second 3-metre shaft.

Characteristics

Location

Located at the dry-stone hut of the Vinya del Tità at Pla d'Ardenya. We will follow the path heading towards the quarry; after covering 425 metres (ETRS89 coordinates 409505-4579038), on the left-hand side of the path a small trail starts which after 235 metres comes out at an open area without vegetation that looks like an old crop field. On the West side of the field a torrent arrives that comes down from the carena de les Alzines; going up the torrent 49 metres we will reach the entrance of the pit, which opens at the foot of two rather large pines.

Description

Morphology

A circular entrance approximately one metre in diameter gives way to a 4-metre-deep shaft. The floor forms a gallery where at the other end and between a large block we find the very narrow entrance of a second 3-metre-deep shaft with the floor full of blocks.

History

First exploration carried out by the ERE of the AEC.

The first time it is mentioned is in a list of cavities in an article by Ferran Elias published in 1973 in the III Simpòsium d'Espeleologia.

In 1979 it appears catalogued but without a survey in the Catálogo Espeleológico del Pla d'Ardenya by Jordi Lloret. That same year it appears catalogued but with a survey by A. Asensio and A. Anibarro in the “Ensayo al catálogo espeleológico de Ordal” by A.Tolrà.

In 2004 it appears catalogued in the Catàleg Espeleològic del Massís de l'Ordal by F. Rubinat, with a survey different from the one already published, but made by the same authors as the previous one.
